Some good reasons to use Red Hat Linux RHEL instead of derivatives CentOS, AlmaLinux, Rocky Linux, SUSE or Oracle Linux

Exploring Red Hat Enterprise Linux: the ideal operating system for advanced business needs that do not mind compromise.



In the vast ecosystem of Linux operating systems, Red Hat Enterprise Linux (RHEL) emerges as a pre-eminent choice, especially for enterprise applications. With a growing number of Linux distributions derived from RHEL, such as CentOS, AlmaLinux, Rocky Linux, SUSE, and Oracle Linux, it is essential to understand the distinctive reasons that make RHEL a superior choice in certain enterprise contexts. This article aims to explore the unique benefits of RHEL in depth, highlighting why it may be preferable over its alternatives for critical business needs.

History and Development of RHEL

Red Hat Enterprise Linux (RHEL), now an integral part of IBM's portfolio following the acquisition of Red Hat, was originally conceived as an ambitious project by Red Hat. Specifically designed to meet enterprise needs for a reliable, secure Linux operating system with long-term professional support, RHEL has been a game changer in enterprise operating systems since its launch in the early 2000s. Its rapid rise and growing adoption by enterprises demonstrate its ability to provide a robust and reliable platform.

Red Hat's commitment, now augmented by IBM's resources and technology expertise, ensured that RHEL stood out in a competitive market. This commitment has extended well beyond simple maintenance, with continuous updates to RHEL to address new challenges and opportunities in the IT industry. Innovations such as virtualization and cloud computing have been integrated into RHEL, making it an increasingly attractive choice for companies engaged in digital transformation.

IBM Red Hat

A key aspect of RHEL, which now benefits from IBM's support and strategic vision, has been its release cycle, which focuses on quality and robustness rather than frequency. Each version of RHEL undergoes rigorous testing and optimization to meet the specific needs of businesses, ensuring an operating system that businesses can have full confidence in for their critical operations.

Additionally, RHEL has shown a remarkable ability to evolve to meet the changing needs of the enterprise market. Whether it was improving performance, optimizing resource use, or integrating new security features, RHEL, under the leadership of Red Hat and IBM, has consistently stayed ahead of the curve, providing businesses with the solutions they needed. need.

The result of these efforts is the consolidation of RHEL as one of the leaders in the enterprise operating systems market.

This makes RHEL not only a high-quality operating system solution, but also a cornerstone in the enterprise IT environment, backed by IBM's long history of innovation and reliability.

Comparison with Derivatives



CentOS has long been a favorite choice for those looking for a RHEL experience without the associated cost, earning a reputation as the free and reliable alternative to RHEL. However, the change in its development model has had a significant impact on its market positioning. The decision to end long-term support for CentOS 8 and the transition to CentOS Stream, which adopts a faster and less stable release model, has created uncertainty among users, particularly those who depend on stability and predictability for their business applications. In the face of these changes, RHEL establishes itself as the most reliable solution, offering the stability and long-term support that enterprises need for their critical operations.

AlmaLinux and Rocky Linux

In response to the CentOS transition, AlmaLinux and Rocky Linux have emerged as modern alternatives, designed to offer a RHEL-like experience without licensing fees. These distributions quickly gained a following among those looking for a replacement for CentOS.
